| Macro: | regxbwsel | |
| Description: | interactive tool for bandwidth selection in univariate kernel regression estimation. |
| Usage: | {hcrit,crit}= regxbwsel(x {,h {,K} {} }) | |
| Input: | ||
| x | n x 2 vector, the data. | |
| h | m x 1 vector, vector of bandwidths. | |
| K | string, kernel function on [-1,1] or Gaussian kernel "gau". If not given, "qua" is used. | |
| Output: | ||
| hcrit | p x 1 vector, selected bandwidths by the different criteria. | |
| crit | p x 1 string vector, criteria considered for bandwidth selection. | |

You may interactively choose the bandwidth selector. The parameters (range of bandwidths, kernel K) can be changed as well.
